Stewart appeared grown up for the first time in 2007, at the L.A. premiere of "Into the Wild." With smoky eyes and blonde hair in a sophisticated updo, Stewart smartly paired a 2006 fall Rodarte chiffon dress with burgundy pumps.

One month after the first "Twilight" film wrapped, Stewart appeared at the 2008 MTV Movie Awards in a modern look—complete with cropped black cigarette cargo pants, a fitted black tank, patent stilettos, and matching jet-black hair.

Then-18-year-old Stewart posed with future beau Robert Pattinson at the 2008 MTV Video Music Awards in a Phillip Lim mini-dress. The press tour kicked off a fashion-forward frenzy for Stewart, who subsequently wore dresses by Temperley London, La Perla, and DKNY.

Forever thumbing her nose at tradition, Stewart has trademarked the Converse-with-dresses look. At the 2009 MTV Movie Awards, Kristen paired a Yigal Azrouël dress with beat-up sneakers. Only this week did she elaborate on her go-to footwear. Wearing flats, she says, helps her sign more autographs when she attends premieres. And that many actresses are “more concerned about looking pretty in your heels, and so you’re walking slowly down the line. Put a pair of sneakers on.”

At the 2009 Teen Choice Awards, she wore a Rock and Republic mini-dress with a spiky skirt and deep V-neck, along with a pair of peep-toe ankle boots by Jerome C. Rousseau. Combined with her mullet cut (in the process of growing out) from her role as Joan Jett in "The Runaways," Stewart stands out from the rest of the crowd.

At the 2011 MTV Movie Awards, Stewart rocked a red micro-mini-dress by Balmain—covered in safety pins and sequins. MTV Style reported on her look, referring to Stewart as a pro “when it comes to complementing hard edges with sophisticated silhouettes.”

Stewart wore a fitted, long-sleeved Zuhair Murad dress to the Toronto Film Festival in 2012 to promote "On the Road." The elaborate dress, complete with sequin flowers decorating the sleeves and suggestively sheer upper bodice and lace skirt, was worn only days after Balenciaga announced her as the face of the Spanish fashion house.

With rumors flying that Kristen Stewart and Robert Pattinson have recently gotten back together, the actress showed up on "The Tonight Show With Jay Leno" in a bright patterned dress by British designer Peter Pilotto. Though she has refused any discussion of her private romantic life, her suddenly colorful wardrobe and giant smile speak volumes.

Just a few weeks ago, this look was coming down the Balenciaga runway as Stewart watched. But she looked stunning in the two-piece pant and top at the AFI premiere of "On the Road" in Los Angeles last week (which, for the record, earned her a spot on our coveted "Best Dressed" list).

Stewart caused a frenzy on the red carpet of the official "Twilight Saga: Breaking Dawn—Part 2" premiere at the Nokia Theatre in Los Angeles on Monday night. She sparkled in a gold Zuhair Murad bustier dress and Jimmy Choo heels.
